BP are nocturnal animals and do not require UV light so that is the thing you can turn off and get rid off.

Now you mention heat mat however you do not mention a thermostat, do you have one?

As far as temps I would lower the hot side a bit to 32/33 maximum 35 is really too much, and cool side is fine between 25/28 however if the cool side is 30 I would actually do away with a hot spot all together 30.

Humidity at 80% is really high and not recommended too high of humidity can be as bad as too low.

How do you measure all that (temps and humidity) do you have some analog devices or digital ones? And where do you take your measurement (up on the top, the middle, or at the floor level)?
